Interventional Radiologist
Image-guided procedural physician. Performs percutaneous and endovascular procedures — biopsy, drainage, embolization, TACE, Y-90, RFA, angioplasty, stenting, vertebroplasty, biliary and GU interventions, port placement, and stroke thrombectomy at comprehensive stroke centers. Works across interventional radiology suites, hybrid ORs, and occasionally the cath lab (for peripheral vascular cases). MD with diagnostic radiology training plus interventional fellowship.
Daily responsibilities
- Procedural work — image-guided biopsies, drain placements, embolizations, stent placements, thrombectomies.
- Pre-procedural consultation — reviewing cross-sectional imaging, consenting patients, procedure planning.
- Post-procedural follow-up — inpatient rounds, clinic visits for longitudinal patient management.
- Consulting referring services — oncology, vascular surgery, hepatology, urology, gastroenterology, orthopedic.
- Resident / fellow teaching (academic practice).
- Call coverage — stroke, GI bleed, trauma embolization, biliary sepsis.
- Quality — procedural outcomes, complication rates, state radiation registration, ALARA compliance.
What they evaluate when equipment decisions come up
- Imaging chain quality — DSA performance, 3D rotational angiography, cone-beam CT (CBCT). Azurion ClarityIQ vs Artis Q vs Innova 4100-IQ.
- Table ergonomics and sterile workflow — cable routing, sterile-field integrity, table-side control placement.
- Dose management — patient dose and operator dose. ClarityIQ and equivalent dose-reduction chains.
- Software — bolus tracking, vessel analysis (iFR / FFR integration), CBCT reconstruction, stent deployment assist.
- Case-mix flexibility — a universal IR room (Azurion 7, Artis pheno, Discovery IGS) handles cardiac-adjacent, peripheral, neuro, and oncologic IR on a single platform.
- Biplane availability — for complex neurointerventional (aneurysm coiling, AVM, stroke thrombectomy).
- Hybrid-OR integration — navigation systems, anesthesia workflow, surgical team coordination.
Decision drivers
- Imaging quality at clinical dose — the core trade-off. Operator preference between platforms is usually dose-reduction-and-image-quality driven.
- Dose to self + patient — IR physicians accumulate substantial occupational radiation dose over a career; dose-reduction platforms materially affect career radiation burden.
- Room efficiency — throughput per day, sterile-reset time.
- Flexibility across procedure types — multi-purpose rooms serve a wider referrer base.
- Training / preference — physicians self-select into labs with platforms they trained on.
